Test Methods for the Transmax Resveratrol Supplement 

Resveratrol supplements were tested for their total trans and cis-Resveratrol content. All products were first analyzed in an independent laboratory using HPLC (High Performance Liquid Chromatography) assay. Products not passing this initial assay were tested in a second independent laboratory utilizing a similar HPLC assay. Biotivia's Transmax resveratrol supplement passed all scientific studies.

Analyses for lead and cadmium were performed using an ICP-MS (inductively Coupled Plasma-Mass Spectroscopy)

Disintegration of non-chewable, no capsule, no enteric coated and non-time-release formulations were analyzed utilizing USP (United States Pharmacopeia) recommendations entitled "Disintegration of Dissolution of Nutritional Supplements".

The identities of the products were not disclosed to the laboratories performing the testing.

To pass, a product must:

1. Must meet 100% resveratrol label claims for the total amount of Resveratrol and specific Resveratrol forms. Total Resveratrol = sum of (total free trans/cis-resveratrol) + (total trans/cis-polydatin) x 0.587 (note. polydatin glycoside is composed 58.7% Resveratrol).
2. Not exceed California Prop 65 levels for lead contamination in a recommended daily serving and in no event, exceed 2mcg of lead in a recommended daily serving.
3. Contain less than 0.3 parts per million (or micrograms per gram) of cadmium for dried raw herb (World Health Organization. Quality Control Methods for Medicinal Plant Material, proposed guidelines 1998) or less than 0.1 parts per million for extracts. The lower concentration standard for extracts reflects the ability to remove heavy metals such as cadmium during the extraction process.
4. Meet recommended USP parameters for disintegration for dietary supplements (excluding capsule, enteric coated, chewable and time-release-products).
5. Product must meet all FDA labeling requirements.
